PRINTING-PRESS..

SPECIFICATION forming part of Letters Patent No. 626,965, dated .T une 13, 1899.

Application filed July 11, 1898. Serial N0. 685,587. (No model.)

To all whom t may concern,.- v

Be it known that I, LAURIS L. CARSON, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Printing-Presses, of which improvements the 4following is a specification.

In an application, Serial No. 684,372, filed on or about June 24, 1898, I have described and claimed certain improvements in attachments for printing-presses for the purpose of preventing the fraudulent return of unsold papers to the publishers. The improvements set forth in said application consist, generally stated, in partially severing or isolating a portion or portions of one or more pages of the paper and then causing such isolated or partially-severed portion or portions t0 adhere tightly to an adjacent sheet or page, whereby a total severance of the partiallysevered portion or portions must be effected before the pages so connected can be separated for perusal.

The invention described herein relates to certain improvements in the mechanism for effecting a partial severance or isolation of a portion or portions of one or more of the pages and causing such portion or portions to adhere to the adjacent page.

The invention is hereinafter more fully described and claimed.

. In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view ot' the portion of a printing-press through which the printed webs pass just prior to their arrangement one upon the other and the folding of the segregated webs. Fig. 2 is a sectional elevation of a portion ofthe press shown in Fig. 1, the plane of section being indicated by the lines II II, Fig. 1. Fig. 3 is a View in elevation, on an enlarged scale, of the severing and pasting mechanism embodying myimprovements. Fig. a is a view, partly in elevation and partlyin section, the plane of section being indicated by the line IV IV, Fig. 3. Fig. -5 is a view similar to Fig. 3, showing a modified construction of being indicated by the line of section Vt' Vt', Fig. 5.

While my improvement is shown in connection with that style or kind of I-Ioe press in which a double web a of paper passes to and through a suitable slitting mechanism, and the portions b and c of the divided web separate and pass around guides 1 and 2, and thence around rollers 3 and 3 and 4 and 4, and then come together one upon the other and pass around a roller 5 to the folding mechanism, it is as readily applicable to other forms or constructions of presses. Asit is customary for the newsdealers to return to the publishers portions of the outside sheet of unsold papers, my improved mechanism is shown so attached to the frame of the press as to operate upon the web, as b, which will form the outside sheet of the completed paper. This mechanism consists of two rolls 6 and 7, secured upon the hubs of intermeshing pinions 8 and 9, which are loosely mounted on pins 10 and 11, secured in a frame 12. As clearly shown in Figs. 1, 2, 3, and 5, this frame is provided with eyes or sockets 13, adapted to slide upon guide-pins 14., hav-V ing their outer ends firmly secured to the frame of the press. The frame 12 and the parts carried thereby are adapted to be shifted along the pins 14 by means of aleverl, connected to the frame 12 by a link 16. The roll 7 is provided with perforations through its perimeter for the entrance of a series of the perforating-needles 17, carried by the roll 6. The needle 17 and the perforations in the opposing roll are arranged so as to form a line or series of perforations in the web or sheet, that a portion thereof may be easily detached without any injury to other portions of the sheet. These needles 17 are secured in a head 18, provided with a stem 19, arranged to move back and forth in suitable guides, formed on the web of the roll, in such man-l ner that the needles will move back and forth through suitable openings in the rim of the roll 6, as clearly shown in Figs. 3, 4., 5, and 6. In the construction shown in Figs. 3 and 4 the stem 19 is surrounded by a spring 21, bearing at its ends against a shoulder on the stern of one of the guide-bearings 20. This IOO Vss

' they will have a peripheral speed equal to the plying mechanism the needles 17 will be with-1 spring serves to hold the inner end of the stem 19 against the surface of a cam 22, secured upon the pin 10, around which the roll 6 and its guidingpin 8 revolve. The cam 22 is so constructed that during part of the revolution of the roll G the needles 17 willbe forced out through the rim of the roll and during the remainder of the revolution of the roll will be drawn within or flush with the outer surface of the rim, for a purpose to be hereinafter described. On the surface of the roll Gand closely adjacent to the perforating-needles is secu red a block 23, preferably having a surface shape corresponding to the shape of the portion of the web or sheet to be isolated, but somewhat smaller in area. This projection or block is designed to apply paste to the partially-severed portion orportions of the Web, so that when the web b is superposed upon the web c as theypass around the guiderollers 5 this partially-severed portion would be caused to adhere to the web c. In order to apply paste or other adhesive material to the surface of the block or projection 23, a paste-receptacle 24 is secured to an arm or extension 25 of the frame l2, preferably immediately above the center of the roll 6. The lower end of this paste-receptacle is closed by a roller 26, adapted to be rotated step by step by a lever 27, operating through a pawland-ratchet mechanism, as described in the application above referred to. The roll 7 simply serves as a support for the web during the perforating and pasting operations.

The rolls G and 7 are driven through any suitable form of gearing from one of the driven portions of the printing-press, so that speed of the webs through the press and in the same direction.

Referring tothe construction shown in Figs. 3 and 4A, it will be seen that as the needles 17 and block 23 move up toward the paste-apdrawn within the rim of the rolls 6, so as to prevent the application of paste to their points. As the roll continues to rotate the needles will be forced out by the cam 22, so as to be ready to operate and form a line of closely-adjacent perforations through the web l). l

In the construction shown in Figs. 5 and 6 the needles 17 are moved positively in and out of operative position by means of a camgroove 28, formed in the side of the disk 29, secured on the pin 10. The stem 1E)y of the head 18 is provided at its lower end with a projection 30, having an antifriction-roller mounted thereon, so as to project into the cam-groove in the disk.

I claim herein as 'my invention- 1. A feed mechanism for printing-presses constructed to effect the onward movement of two webs or sheets of paper and to arrange such webs or sheets against each other, in combination with a pair of rolls arranged on oppositesides of the path of movement of one of said webs or sheets, a series of needles carried byone of said rolls and arranged to partially sever or isolate a portion of said web or sheet, and means for shifting said needles into and out of operative position, substantially as set forth.

2. A'feed mechanism for printing-presses constructed to effect the onward movement of two Webs or sheets of paper and to arrange such webs or sheets against each other, in combination with a pair of rolls arranged on opposite sides of the path of movement of one of said webs or sheets", a series of needles carried by one of said rolls and arranged to partially sever or isolate a portion of said web or sheet, means for shifting said needles into and out of operative position, means for applying paste to one of the sheets in such manner that the severed orisolated portion of one web or sheet will adhere to the other web or sheet when the webs or sheets are placed together, substantially as set forth.

3. A feed mechanism for printing-presses constructed to effect the onward movement of two webs orsheets of paper and to arrange said webs or sheets against each other, in cornbination with a positively-driven roll having a peripheral speed equal to that of the movement of the' paper through the press and arranged in the path of movement of one web or sheet, a series of needles carried by said roll and arranged to partially sever or isolate a portion of said web or sheet, and a stationary cam for shifting said needles, substantially as set forth.

A feed mechanism for printing-presses constructed to effect the onward movement of two webs or sheets of paper and to arrange such webs or sheets against each other, in combination with a roll arranged in the path of movem ent of one of the webs or sheets., a series of needles carried by said roll and arranged to partially sever or isolate a portion of the web or sheet, means for shifting the needles into and out of operative position during the rotation of the roll, a paste-applying block arranged to operate on the partially severed or isolated portion of the sheet or web, and means operated by the roll for applying paste to the block, 'substantially as set forth.

In testimony whereof I have hereunto set my hand.
